The clutch, designated generally by the r `numeral 13, of the improved starter 1s mounted upon the forward end of the crank shaft `8 and includesan annular retaining sleeve 14, rigidly secured to the crank shaft 8jby a locking pin 15. An annular clutch member 16 is positioned over the sleeve 14 and is secured against rotary movement with relation to the shaft 8 by the locking pin 15, which extends therethrough` The outer sur`- face of the clutch member 16 is formed with spaced flanges 17, providing a groove adapted to receive the fan belt 12, whereby thefan 10 is operated during rotation of the crank shaft 8. `The front face of the clutch member 16 is formed with an annular groove or channel 18 in which is mounted a pluralityA of spaced clutch balls 19.

. `The other clutch member 20 is of annular formation and 's rotatably mounted upon thefsleeve llforwardly of the clutch mem ber 16"and is confined between the latter and anexternalflange 21 formed adjacentthe forward endof the sleeve`14. The rear por` tion of the clutch member or ring 20 dis-` posed .within the channel 18 is formed with a` plurality of ratchet teeth 22 having inclined and radial faces 23 and 24:, respectively, with which the clutch balls 19 Aare .curved` outer extremityioi the .partof the:

ratchet teeth 22 and the clutch member 16 so as to lock the parts of the clutch against relative rotary movement in one direction. The operating arm 27 isreturned to initial position, subsequent to an operation thereof, by the tension of a coil spring 28, fastened at one end to thearm 27 land at-its-opposite end to a part of the vehicle chassis 5.

An operating cable, chain, or other lflexible element 29 is connected at one end With the tends across the front of the engine, under guide pulley the driver of the vehicle.` A a 4 a 'The .swingingmovement Qi'. the @painting arm 27 under lthe, influence ofthespring 28 4is, limited by a relatively short arm`34` carried by1an annular 'ball releasingjmember fitted between the flange .25;z`indf4 the ffoif- Ward end of theclutch member 16 "and adapted to engage relativelyrstationary vehicle chassis, as illustrated in Fig.y l.
